Description
P0429R9 introduced the following using
aliases in [container.adaptors.general]:
The following exposition-only alias templates may appear in deduction guides for container adaptors:
template<class Container> using cont-key-type = // exposition only remove_const_t<typename Container::value_type::first_type>; template<class Container> using cont-mapped-type = // exposition only typename Container::value_type::second_type;
But I didn't find these two being used anywhere. Any information or am I missing something?

They were used in P0429R8 but are meaningless now...
